Stepper Motor - What's inside?

The video tutorial explains the structure and function of a hybrid motor, focusing on its main components: the rotor and stator. The rotor, a permanent magnet, interacts with the stator's electromagnetic fields to create rotation. The motor's precision is enhanced by the alignment of teeth on the rotor and stator, which are offset to ensure smooth operation. The video also details how the coils in the stator are energized to create magnetic fields, causing the rotor to turn in precise steps. This design allows for high precision and torque in motor operation.

Describe the role of the coils in the stator.

What is the significance of the difference in the number of teeth between the rotor and stator?
